In Mexico May 23, 1934' Claims.

My invention relates to a carton edge protector and tie retainer devicedesigned primarily for use in connection with cartons of the corrugatedpaper type, but it is to be understood that a de- 5 vice, in accordancewith my invention, may be employed in any connection for which it isfound applicable.

The essential objects of my invention are to provide, in a manner ashereinafter set forth, a device of the class referred to for protectingthe edges of the walls and for reinforcing the corners of a carton ofthe corrugated paper type; for preventing the tie employed formaintaining the walls of the carton around the contents of the lattershifting from its initially set position; for protecting and concealingthe tie at the corners of the carton; for preventing the crushing of thecarton by the tie; for preventing the crushing of the corners of thecarton by the tie; for preventing the carton from being distorted by thetie during the tying operation; for preventing the crushing of thecontents of the carton by the tie during the tying operation and afterthe tie has had its ends anchored or secured together.

Further objects of my invention are to provide, in a manner ashereinafter set forth, a device for the purpose set forth which issimple in its construction, strong, durable, compact, readily installedwith respect to a carton for conveniently receiving the tie for thelatter, thoroughly efficient in its use and inexpensive to manufacture.

With the foregoing and other objects in view, my invention consists ofsuch parts and such combination of parts as are hereinafter morespecifically described and as illustrated in the accompanying drawing,wherein is shown an embodiment of the invention, but it is to beunderstood that changes, variations and modifications may be resorted towhich fall within the scope. of the invention as claimed.

In the drawing:

Figure 1 is a perspective view of the device extended prior to itsapplication,

Figure 2 is a top plan view of the device extended prior to itsapplication,

Figure 3 is a view looking towards one of the end edges of the devicewhen extended,

Figure 4 is a view looking towards one of the side edges of the devicewhen extended, and

Figure 5 is a fragmentary view, in perspective, of a corrugated papercarton, the tie for the latter and illustrating the installation of mycarton edge protector and tie retainer with respect to the carton andtie.

Referring to the drawing, there is illustrated,

by way of example, for the purpose of showing the-application of mydevice, the top and the end walls 6, 1 respectively of a corrugatedpaper carton and a tie 8 for maintaining the carton closed and formaintaining the Walls of the latter in encompassing. relation Withrespect to the contents, not shown, of the carton. One end of the wall 6seats upon the top edge 9 of the wall 1. The edge of the latter isdesignated I9.

The carton edge protector and tie retainer device, in accordance with myinvention, is formed from a rectangular foldable or bendable plate I Iof sheet metal of the desired gauge, having beveled side and end edgesI2, I3 respectively.

The device includes a pair of rectangular wings I l, I5 disposed atright angles to each other and which, at their inner sides, merge intothe sides I6, ll of'a rounded coupler I8 which is outset at aninclination with respect to the inner sides I9, 22E! of the Wings l4, l5respectively. The coupler 18 forms a groove 2i for receiving the edgeII] of wall 6. The wing M is horizontally disposed and the wing I5 isvertically disposed. The wings M, I5 are positioned against the outerfaces of the walls 6, I respectively.

The wing I iis formed with a pair of oppositely disposed aligningV-shaped slits 22 extending lengthwise thereof. The material freed bythe slits 22 is bent inwardly at right angles to the body of the wing I4to provide a pair of V-shaped fastener barbs 23 for extension into thewall 6 for anchoring wing I4 thereupon.

The wing I5 is provided with a pair of spaced parallel V-shaped slits 24extending transversely thereof. The material freed by the slits 24 isbent inwardly at right angles to the body of wing I5 to provide a pairof V-shaped fastener barbs 25 for extension into the wall I foranchoring wing I5 thereupon. Preferably the barbs 25 will be of lessarea than the barbs 23.

The wings I4, I5, on the transverse medians thereof and in proximity tothe sides I9, 20 respectively, are provided with the circular openings2B, 21 respectively for the passage of the stretch 28 of the tie 8. Thestretch 28 passes under the coupler I8 and is protected by andsubstantially concealed by the latter. The walls of the openings 26, 21prevent the shifting of the stretch 28 laterally upon the corner of thecarton after the tie has been set and strung through wings l4, I5.

The coupler I8 preferably is formed with a row of spaced openings 29 tofacilitate the rounding thereof.

It is to beunderstood that the carton will be provided at each end withone of the devices arranged in the manner as shown in Figure 5. Thedevices, when anchored in position upon the carton, will prevent thecrushing of the corners and walls of the carton by the tie due to themanner in which the tie is strung through and arranged relative to thewings I 4, l5, that is to say, the stretches 28 of the tie are arrangedunder the couplers by the passage of such stretches through the openings26, 21 and other stretches 30, 3| bear against the outer faces of thewings M, I 5. As the devices not only prevent the crushing of thecorners of the carton, but alsd the crushing or distorting of the wallsof the carton, it naturally follows that the contents of the carton arenot crushed or distorted.

What I claim is:

1. A carton edge protector and tie retainer device comprising a pair ofspaced wings disposed in angular relation, a rounded coupler integral atits sides with the inner sides of and outset with respect to said wings,each of said wings being formed with an opening in proximity to itspoint of jointure with a side of said coupler, said wings having theiropenings extending in opposite directions with respect to each other,and each of said wings having right angularly disposed inwardlyextending portions providing fastener barbs.

2. A carton edge protector and tie retainer comprising a pair of spacedwings disposed at right angles to each other and adapted to seat againsta pair of walls of the carton, a coupler outset at an inclination withrespect to, arranged between and integral at its sides with the innersides of said wings, said coupler being rounded to form an inwardlyarranged groove to receive a corner of the carton, said wings beingformed with openings in proximity to their points of mergence with saidcoupler for disposing a stretch of the tie under said coupler, and eachof said wings being formed with spaced inwardly extending fastener barbsfor anchoring it to one of said walls.

3. A carton edge protector and tie retainer comprising a pair of spacedwings disposed at right angles to each other and adapted to seat againsta pair of walls of the carton, a coupler outset with respect to,arranged between and integral at its sides with the inner sides of saidwings, said coupler being rounded to form an inwardly arranged groove toreceive a corner of the carton, said wings being formed with openings inproximity to the sides of the coupler for disposing a stretch of the tieunder said coupler, one of said wings having lengthwise portions thereofproviding fastener barbs for anchoring it to one of said walls, and theother of said wings having transverse portions thereof providingfastener barbs for anchoring it to the other of said walls.

4. A carton edge protector and tie retainer device comprising a pair ofspaced wings, a rounded coupler integral at its sides with the innersides of and outset at an inclination with respect to said wings, eachof said wings being formed with an opening in proximity to the side ofthe coupler, and each of said wings having right angularly disposedinwardly extending portions providing fastener barbs, the barbs of onewing being disposed at right angles to the barbs of the other wing.

5. A carton edge protector and tie retainer comprising a pair of spacedwings disposed at right angles to each other and adapted to seat againsta pair of walls of the carton, a coupler outset with respect to,extending in a plane at an inclination to, arranged between and integralat its sides with the inner sides of said wings, said coupler beingrounded to form an inwardly arranged groove to receive a corner of thecarton, said wings being formed with openings in proximity to the sidesof the coupler extending in directions at right angles to each other fordisposing a stretch of the tie under said coupler, each of said wingsbeing formed with a pair of spaced fastener barbs for anchoring it toone of said walls, the barbs of one wing being disposed at right anglesto the barbs of the other wing.
